(1) Air conditioner The air conditioner 3 is comprised of the indoor units 2a, 2b, 2c and the outdoor unit 20, and can perform air conditioning operations including cooling operation and heating operation. Indoor heat exchangers 4a, 4b, 4c, indoor fans 5a, 5b, 5c and the like are accommodated in the indoor units 2a, 2b, 2c. The indoor heat exchangers 4a, 4b, and 4c exchange heat with the air in contact with them to generate conditioned air. The indoor heat exchangers 4a, 4b, and 4c function to function as a refrigerant evaporator during cooling operation to cool the air taken in, and during the heating operation, function as a refrigerant condenser to remove the air taken in. Heat. The indoor fans 5a, 5b, and 5c suck the air in the air-conditioning target space, pass it through the heat exchanger, and discharge the conditioned air after the heat exchange is performed into the air-conditioning target space. Moreover, indoor unit control part 61a, 61b, 61c is incorporated in indoor unit 2a, 2b, 2c. Indoor unit control part 61a, 61b, 61c receives the control command transmitted from air-conditioning control device 60, and indoor heat exchanger 4a, 4b in indoor units 2a, 2b, 2c based on the received control command , 4c and indoor fans 5a, 5b, 5c and the like.

In addition, the communication unit 63 transmits the control command received from the control unit 64 to the indoor unit control units 61a, 61b, 61c and the outdoor unit control unit 62.

  The storage unit 65 stores an operation stop time of the air-conditioning operation within a predetermined period (for example, one month).

  The control unit 64 transmits, to the communication unit 63, a control command for the operation details performed by the air conditioner 3 based on the instruction information from the air conditioning target person transmitted from the communication unit 63. The control command for the operation content is, for example, a control command for starting or stopping the air-conditioning operation, changing the set temperature or the set air volume, and starting the energy saving control. Moreover, energy saving control is control performed at the time of air conditioning operation in order to suppress the power consumption of the air conditioner 3. In the present embodiment, the energy saving control is control for performing forced thermo-off.

  Further, at the time of air conditioning operation, the control unit 64 is based on the indoor temperature value obtained from the indoor temperature information detected by the room temperature thermistor and the outdoor air temperature value obtained from the outdoor air temperature information detected by the outdoor air temperature thermistor. It is determined whether or not the indoor environment is comfortable. Further, the determination by the control unit 64 is performed every predetermined time (for example, 3 minutes). Note that whether or not the indoor environment is comfortable is determined based on the comfortable range W shown in FIG. The comfortable range W is a range in which the indoor temperature value> the outdoor air temperature value + 5 in the heating operation, and a range in which the indoor temperature value <the outdoor air temperature value−5 in the cooling operation. When it is determined that the indoor environment is not comfortable, the control unit 64 transmits a control command to the communication unit 63 so that the indoor temperature value X is within the comfortable range W. Further, in the present embodiment, the comfortable range W is set based on the indoor temperature and the outside air temperature, but is limited to this as long as it is an index for determining whether or not the indoor environment is comfortable.

  The control unit 64 determines the median value of the normal distribution calculated by the prediction unit 64c as the scheduled operation stop time T2 during the air-conditioning operation (step S1). Moreover, the control part 64 determines the start time T1 of energy saving control. When the current time reaches the energy saving control start time T1, a control command for starting energy saving control is transmitted from the communication unit 63 to the indoor unit control units 61a, 61b, 61c and the outdoor unit control unit 62. When a control command for starting energy saving control is transmitted from the communication unit 63, the indoor unit control units 61a, 61b, 61c control various devices in the indoor units 2a, 2b, 2c, and the outdoor unit control unit 62 is controlled by the outdoor unit 20.

When an operation stop control command is transmitted from the communication unit 63, the indoor unit control units 61a, 61b, 61c control various devices in the indoor units 2a, 2b, 2c, and the outdoor unit control unit 62 is in the outdoor unit 20. Air conditioning operation is stopped by controlling various devices.

  In addition, when there is an instruction from the air conditioning subject via the controller 50 until the current time reaches the scheduled stop time T2, the control unit 64 determines whether the instruction content is an operation stop instruction of the air conditioner 3. It is determined whether or not (step S5). When the instruction content is an instruction to stop the operation of the air conditioner 3, an operation stop control command is transmitted from the communication unit 63 to the indoor unit control units 61 a, 61 b, 61 c and the outdoor unit control unit 62. The indoor unit control units 61a, 61b, and 61c control various devices in the indoor units 2a, 2b, and 2c, and the outdoor unit control unit 62 controls various devices in the outdoor unit 20 to perform air conditioning operation. Stop. Further, when the instruction content is an instruction other than an instruction to stop the operation of the air conditioner 3 (for example, a change in set temperature) P1 (see FIG. 5), the communication unit 63 to the indoor unit control units 61a, 61b, 61c, and A control command for canceling energy-saving control and a control command based on this command are transmitted to the outdoor unit control unit 62 (step S6). Then, based on the control command transmitted from the communication unit 63, the indoor unit control units 61a, 61b, 61c control various devices in the indoor units 2a, 2b, 2c, and the outdoor unit control unit 62 is in the outdoor unit 20. Control various devices. In addition, the air conditioning operation is performed until an instruction to stop the operation is issued by the air conditioning subject. When the air conditioning target gives an instruction P2 to stop the air-conditioning operation, the communication unit 63 notifies the indoor unit control units 61a, 61b, 61c and the outdoor unit control unit 62 to stop the air-conditioning operation. A control command is transmitted (step S4 and step S7). When a control command for stopping operation is transmitted from the communication unit 63, the indoor unit control units 61a, 61b, 61c control various devices in the indoor units 2a, 2b, 2c, and the outdoor unit control unit 62 is in the outdoor unit 20. Air conditioning operation is stopped by controlling various devices.

When a control command for starting operation is transmitted from the communication unit 63, the indoor unit control units 61a, 61b, and 61c control various devices in the indoor units 2a, 2b, and 2c, and the outdoor unit control unit 62 is controlled by the outdoor unit. By controlling various devices in 20, the operation of the air conditioner 3 is started (step S8). Also in this case, the air conditioning operation is performed until the operation stop instruction P2 is issued by the air conditioning target person. P1 and P2 in FIGS. 5 and 6 indicate the time when there is an instruction P1 other than the operation stop from the air conditioning subject and the time when the operation stop instruction P2 is received from the air conditioning subject.

<Features>
(1)
In an air-conditioning target space in which air-conditioning operation is performed, even if the operation of the air conditioner is stopped, comfort may be maintained for a while. Therefore, conventionally, in order to realize energy saving, there is an air conditioning control system that performs stop control for stopping supply of air to the air conditioning target space before a preset operation stop time.

  For example, in the air conditioning control system disclosed in Japanese Patent Application Laid-Open No. 2007-132598, the operation stop time of the air conditioner is determined based on an air conditioning schedule such as a preset day of the week, and stopped retroactively from the operation stop time. When the control is started, a time at which the temperature in the air-conditioning target space at the operation stop time becomes the lower limit value of the preset appropriate temperature range is determined as the control start time.

  By the way, in this air conditioning control system, the operation stop time of the air conditioner is determined based on the air conditioning schedule. For this reason, when the air-conditioning schedule is not set, this air-conditioning control system cannot be used.

  Therefore, in the above embodiment, the control unit 64 functions as the calculation unit 64a and the determination unit 64b. The calculation unit 64a calculates the normal distribution based on the past operation stop time within the predetermined period. In addition, the determination unit 64b determines the calculated median of the normal distribution as the scheduled stop time T2 for operation. Furthermore, the determination part 64b determines the start time T1 of energy saving control. For this reason, when the current time reaches the start time T1 of the energy saving control, the energy saving control can be started.

  As a result, energy saving can be realized even when the schedule is not set.

  Further, the determination unit 64b determines the scheduled operation stop time T2 by using the past operation stop time calculated by the calculation unit 64a. For this reason, the scheduled operation stop time T2 can be determined based on the past operation results of the air conditioner 3.

  As a result, it is possible to save time and effort for the air conditioning target person to set the schedule.

<Modification>
(A)
In the above embodiment, if there is an instruction other than the instruction to stop the operation of the air conditioner 3 from the air conditioning subject through the controller 50 from the start time T1 of the energy saving control to the scheduled stop time T2 of the air conditioning operation, The air-conditioning operation is continued until an instruction to stop the operation is issued by the subject. Further, after the current time reaches the scheduled shutdown time T2 of the air conditioning operation, if there is an air conditioning operation start instruction from the air conditioning subject via the controller 50, the air conditioning subject issues an instruction to stop the operation. Air conditioning operation is continued until However, if there is an instruction other than the air conditioning operation stop instruction from the air conditioning target person from the start time of energy saving control to the scheduled shutdown time or after reaching the shutdown time, stop The scheduled time may be changed after a predetermined time (for example, 30 minutes later) from the time when the instruction is given.

  For example, as shown in FIG. 7, when the scheduled operation stop time T2 and the control start time T1 of energy saving control are determined by the control unit (step S11) and the current time reaches the start time T1 of energy saving control, A control command for starting energy saving control is transmitted to the machine control unit and the outdoor unit control unit. When a control command for starting energy saving control is transmitted from the communication unit, the indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit, thereby saving energy in air conditioning operation. Take control.

  And when there is no instruction | indication from the air conditioning subject through a controller after starting the energy saving control until the present time reaches the scheduled stop time T2, the indoor unit control unit and the outdoor unit control unit from the communication unit In addition, a control command for stopping the air-conditioning operation is transmitted (step S12, step S13, and step S14). When an operation stop control command is transmitted from the communication unit, the indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit to stop the air conditioning operation. .

  In addition, when there is an instruction from the person to be air-conditioned via the controller before the current time reaches the scheduled stop time T2, the control unit determines whether the instruction content is an instruction to stop the air-conditioning operation. Is determined (step S15). If the instruction content is an instruction to stop the operation of the air-conditioning operation, an operation stop control command is transmitted from the communication unit to the indoor unit control unit and the outdoor unit control unit (step S14). The indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit to stop the air conditioning operation. In addition, when the instruction content is an instruction other than the instruction to stop the operation of the air-conditioning operation (for example, change of set temperature) P1 (see FIG. 8), the communication unit sends the indoor unit control unit and the outdoor unit control unit A control command for canceling energy-saving control and a control command based on this command are transmitted. Based on the control command transmitted from the communication unit, the indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit. Further, the control unit changes the time after a predetermined time (for example, one hour) Tw from the time when the instruction from the air-conditioning subject is given as a new scheduled stop time T4 from the predetermined scheduled stop time T2. (Step S16). Further, the control unit again determines the start time T3 of the energy saving control based on the changed scheduled stop time T4. When the current time reaches the determined energy saving control start time T3, a control command for starting energy saving control is transmitted from the communication unit to the indoor unit control unit and the outdoor unit control unit. When a control command for starting energy saving control is transmitted from the communication unit, the indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit, thereby saving energy in air conditioning operation. Take control.

  And when there is no instruction | indication from the air conditioning subject through a controller after starting the energy saving control until the present time reaches the scheduled stop time T4, the indoor unit control unit and the outdoor unit control unit from the communication unit In addition, a control command for stopping the air-conditioning operation is transmitted (step S12, step S13, and step S14). When an operation stop control command is transmitted from the communication unit, the indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit to stop the air conditioning operation. .

  In addition, when there is an instruction from the air conditioning subject through the controller until the current time reaches the scheduled stop time T4, the control unit determines whether the instruction content is an instruction to stop the air-conditioning operation. Is determined (step S12 and step S15). If the instruction content is an instruction to stop the operation of the air-conditioning operation, an operation stop control command is transmitted from the communication unit to the indoor unit control unit and the outdoor unit control unit (step S14). The indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit to stop the air conditioning operation. In addition, when the instruction content is an instruction other than an instruction to stop the air-conditioning operation (for example, a change in set temperature), a control command for canceling energy saving control is transmitted from the communication unit to the indoor unit control unit and the outdoor unit control unit. And a control command based on this instruction is transmitted. Based on the control command transmitted from the communication unit, the indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit. In addition, the control unit changes the time after a predetermined time (for example, one hour) from the time when the instruction from the air-conditioning subject is given as a new scheduled stop time from the predetermined scheduled stop time. In this way, the air-conditioning operation is performed until the current time reaches the scheduled operation stop time or until an operation stop instruction is issued from the air conditioning subject.

  Also, after the current time has reached the scheduled stop times T2 and T4, if there is an air conditioning operation start instruction from the air conditioning subject via the controller, the communication unit operates the indoor unit control unit and the outdoor unit control unit. A start control command is transmitted (step S17). When a control command for starting operation is transmitted from the communication unit, the indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit. Operation starts. In addition, the control unit determines a time after a predetermined time (for example, one hour) from the time when the operation start instruction is received from the air conditioning target person as the scheduled stop time (step S18). Further, the control unit determines the energy saving control start time based on the scheduled stop time. When the current time reaches the start time of energy saving control, a control command for starting energy saving control is transmitted from the communication unit to the indoor unit control unit and the outdoor unit control unit. When a control command for starting energy saving control is transmitted from the communication unit, the indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit, thereby saving energy in air conditioning operation. Take control.

  And if there is no instruction from the air-conditioning target person via the controller from the start of energy saving control until the current time reaches the scheduled stop time, the communication unit sends it to the indoor unit control unit and the outdoor unit control unit. Then, a control command for stopping the air-conditioning operation is transmitted (step S12, step S13 and step S14). When an operation stop control command is transmitted from the communication unit, the indoor unit control unit controls various devices in the indoor unit, and the outdoor unit control unit controls various devices in the outdoor unit to stop the air conditioning operation. . If there is an instruction from the person to be air-conditioned via the controller until the current time reaches the scheduled stop time, the process proceeds to step S14 through steps S12 and S15, or steps S12 and S15. And step S16 is repeated. In addition, after the current time has reached the scheduled stop time, if there is an air conditioning operation start instruction from the air conditioning target person via the controller, the process goes from step S12 to step S14 through step S17 and step S18. Or, through Step S17 and Step S18, Step S12 is reached again via Step S12, Step S15 and Step S16.

  As a result, even if there is a command from the person to be air-conditioned from the start time of the energy saving control to the scheduled shutdown time or after reaching the scheduled shutdown time, the new scheduled shutdown time and the new energy saving The start time of control can be determined.
